What is JIT Compilation?

  • A JIT (Just-In-Time) compiler converts the MSIL (MS Intermediate Language) into native code on demand during the application runtime, when the application components are loaded and executed.
  • The JIT compilation happens specific to the running CPU architecture, since the common language runtime supplies a JIT compiler for each supported CPU architecture.
  • If the managed code calls platform-native APIs or runs platform-specific assemblies, the JITed code runs on only that particular system.
